Audited Supplier Description
850nm Narrow Bandpass Filter transmit light only within a defined spectral band ranging from less than one to many nanometers wide. They are used in a wide variety of applications where spectral isolation is required. Bandpass filters are preferable to monochromators because of their higher transmission and better signal-to-noise.
Standard or customized features with different functions for the special applications.
940nm Narrow Bandpass Filter compatibly used with 940nm LED light or laser light source, which the image sensor only requires a small bandwidth of the 940nm NIR light to for the black and white image.
Band pass filters are typically constructed of a clear or absorptive filter glass coated with a dielectric multi-layer coating that rejects energy outside of the pass band. Short pass filters pass regions that are shorter in wavelength (higher in energy) that the blocking (or stop) band. Long pass filters pass regions that are longer in wavelength (lower in energy) that the blocking band. Notch filters incorporate stop bands at lower and higher energies than the pass band.
